Leukotriene Inhibitors for Asthma and Allergies

Asthma and Allergic Rhinitis

Asthma
is a chronic lung disease. When asthma strikes, airways in the lungs become swollen and constricted, causing coughing, wheezing, and difficulty breathing.

Allergic rhinitis, also called hay fever,
is an allergic response by your immune system to pollens, mold, and dust. Symptoms include stuffy, runny, or itchy nose, and sneezing.

Asthma and allergic rhinitis can be triggered by many of the same allergens. And, in both conditions, leukotrienes add to the development of symptoms. Leukotrienes are chemicals that cause inflammation, mucous secretion, and constriction in your lungs.

Types of Leukotriene Inhibitors

Leukotriene inhibitors are medicines that decrease inflammation by preventing the action of leukotrienes. These types of medicines are not used to relieve acute symptoms, but can be used to prevent your symptoms from occurring.

Examples of leukotriene inhibitors that are available include:

Montelukast

Zafirlukast

Zileuton

Side Effects

Some of the most common side effects with these drugs are:

Flu-like symptoms

Nervousness, excitability

Headache

Stomach pain

Cough

While rare, liver problems can occur while taking leukotriene inhibitors. These drugs can also cause mental health problems, like mood or behavior changes. If you are prescribed a leukotriene inhibitor, be sure that you report any side effects to your doctor.

Other Precautions

You may not be able to take a leukotriene inhibitor if you:

Are allergic to any of the ingredients in the medicine

Have other medical problems, such as liver disease

Are taking other medicines, including prescription drugs, over-the-counter drugs, herbs and supplements

If you have asthma or allergic rhinitis and want relief from your symptoms, talk to your doctor or get a referral to an allergy specialist. Depending on your condition and overall health, leukotriene inhibitors may be a good choice for you.
